The article presents a nomogram for determining the value of the heater power providing the operating temperature in the dryer drum of the device, the method of experimentally determining the specific heat capacity of the grain mass and the results of the experiments are compared with the given literary values. The definition of drying time is shown using the obtained nomogram and using the specific heat capacityvalue to calculate the required amount of heat.
